Corrupted Blade

This is NOT a fighter subclass, and you cant pick it, unless your race is Living Blade's subrace - Corrupted blade - made by me, obviously.

 

Living Blades, that got cursed by Tiamat, fight in much different ways, then their pure brothers. They are now able to cast a variety of different spells, including mostly blood, fire and necromantic magic. In melee they tend to move and strike like a beast, and word "tactics" is rarely in their vocabulary. In return, they tend to deal massive damage to wide area with brutal chain of attacks, that make even mountains tremble. You cant wear armor, but get covered in metal-dence scales insdead, which grows only thicker each new level you get. 

Quick Build

You can make a blade quickly by following these suggestions. First, make Strength or Dexterity your highest ability score, depending on whether your weapon body type. Your next-highest score should be Constitution, because the blade is not indestructible and you will be right in the center of each battle!

 If your Master allows the use of traits, you can discard the benefits of this skill when increasing the values of characteristics and take a trait instead.

Blood Infusion

15-th Level, Corrupted Blade Skill, You need a host for this to work.

 You get so expirienced at blood manipulations, that you are now able to influence your host with it. Every time you hit Bleeding enemy, your host gains 1 stack of Blood Infusion. You can store up to 30 of these. Each stack gives that host a +1 to Strenght, Dexterity, and Physique, up to 30 points in each, and grows in size 1ft per stack. Host's skin turns red, scales appear all ower its body, covering back, front, and shoulders. Pair of gigantic dragon horns appear on top of its head. You also learn how to use Draconic Wings, while held by a host, growing a pair of bat-like wings on its spine, increasing your Flying speed to 80ft.

Your host stops losing HP every 3 turns, and does not die after 3 hours without you consuming blood. Instead, you loose 1 stack of Blood Infusion every 3 hours. While in battle, you are now healing 3d4 every three turns. 

Frightful Presence

18-th Level, Corrupted Blade Skill, You need a host with at least 15 stacks of Blood infusion for this to work.

Each creature that is looking at you within 80 feet must succeed on a DC 21 Wisdom saving throw or become Frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, Ending the Effect on itself on a success. If a creature's saving throw is successful or the Effect ends for it, the creature is immune to your Frightful Presence for the next 24 hours.

World Ender

20-th Level, Corrupted Blade Skill, You need a host with at least 20 stacks of Blood infusion for this to work. 

When you use that ability, you take one turn to channel all of your hosts blood into you. At your next turn, you leap 30ft in chosen direction, and land a devastating blow on the ground, or anything above it. That single strike deals 1d100*N damage to anything in 25-foot cube around the place your strike lands, where N - is number of your Blood Infusion stacks. Whenewer you roll less then 25 on a dice, you reroll it, even if you get less then 25 again. Targets outside of impact zone in 100-foot cube get half of that damage, if they fail a DC 15 Dexterity check. In addition, an intense tremor rips through the ground in a 100-foot- radius circle centered on point, where attack landed and shakes creatures and structures in contact with the ground in that area. The ground in the area becomes Difficult Terrain. Each creature on the ground that is concentrating must make a Constitution saving throw. On a failed save, the creature's Concentration is broken.

After landing that attack, your host dies permanenly, and you have 3 hours to find a new one, otherwise you are going to die as well.
